Abstract: 1278469 Polymer compositions L CHICCO and W. KORESKA 30 Oct 1969 [30 Oct 1968], 53299/69 Headings C3B C3C C3P and C3R [Also in Divisions D2 and H1] Various compositions containing polymers are used in the preparation of pressure-sensitive transfer elements. These compositions contain: Example 1 a polyphenylene oxide-polystyrene blend, chloroform and toluene; polyphenylene oxide-polystyrene blend, diphenylphthalate, castor oil, carbon black, kaolin, and chloroform. Example 2 polyphenylene oxide-polystyrene blend, chloroform, toluene, dioctyl phthalate and lithol red; polyphenylene oxide-polystyrene blend, dioctylsebacate, oleic acid, carbon black, ultramarine blue, dichloroethylene, chloroform and toluene. Example 3 polyphenylene oxide-polystyrene blend, a plasticizer, ferrosoferic oxide, toluene and trichloroethylene ; polyphenylene oxide-polystyrene blend, octylepoxy stearate, anhydrite, alkali blue pigment, naphthenic mineral oil, trichloroethylene and toluene. Example 4.-A condensation product of 2,2,4- and 2,4,4-trimethylhexamethyleneamine with terephthalic acid, chloroform and methanol; the same condensation product, tricresyl phosphate, black pigment, azoisobutyric acid dinitrile, castor oil, chloroform and methanol. Example 5.-A condensation product of bisphenol-A and epichlorohydrin, a polyurethane, methylethyl ketone, toluene, and zinc oxide; a vinyl chloride/vinyl acetate copolymer, naphthenic mineral oil, Prussian blue, α - α - azo - diisobutyralnitrile, clay, caster oil, methylethyl ketone and toluene. Example 6.- A polycarbonate resin, a plasticizer and methylene chloride; polycarbonate resin, dioctyl sebacate, silica, alkali blue, castor oil, and methylene chloride. Example 7.-Polycarbonate resin, di-iso-octyl-phthalate, aluminium or bronze powder, methylene chloride and chloroform; a vinyl chloride, vinyl acetate copolymer, a polyurethane, bentonite, naphthenic acid carbon black, methylethyl ketone, tetrahydrofuran. Example 8.-Nitrocellulose, triphenyl phosphate, n-butyl alcohol, toluene and acetone; a vinyl polymer, petrolatum, mineral oil, a magnetic pigment, toluene and ethyl acetate. Example 9.-Polyphenylene oxide-polystyrene trichloroethylene, toluene, iso-propanol and fibres of about 2-3 m.m. of nylon or a polyethyleneterephthalate. Example 10 uses the composition of Example 9 where the copolymer is replaced by a polyphenylene oxide polymer. Example 11.-P.V.C., dioctylphthalate, dioctylsebacate, lead octoate, silica and titanium dioxide; P.V.C., benzyl-butyl-phthalate, a dye, and an azodicarbamide blowing agent. Example 12.-A polyvinyl chloride polymer " Hostalit " (Trade Mark) containing a minor proportion of maleic acid, octyl epoxy-stearate, dioctyl phthalate, dioctyl sebacate, a lead stabilizer, silica, and aluminium powder. Example 13.- P.V.C., benzyl-butyl phthalate, tricresyl phosphate, epoxy-butyl-oleate, a green pigment and titanium dioxide; a polyvinyl polymer, toluene, methyl ethyl ketone, ultramarine blue, alkali blue, phthalocyanine blue, mineral oil, and an expanding agent. Porous products were obtained in Examples 4, 5, 11 and 13.
